SPECIFICATION forming part of Letters Patent No. 621,172, dated March14, 1899.

Application filed October 14, 1895. Serial No. 565,539. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE STIKEMAN, a citizen of the United States,residing at New York, (Brooklyn,) in the county of Kings and vadjustably secured to the upright beams or.

columns of the framework.

This invention has for its object the provision of a novel bracketadapted to be .adjustably attached to a suitable framework and supportthe shelves and it consists in the novel construction and combination ofparts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective Viewillustrating my invention. Fig. 2 is a plan view, partly in section.Fig.

3 is a horizontal sectional view of a modified form of bracket inposition.

The supporting-columns of the structure consist of end columns andintermediate columns. The end columns consist each of a vertical plate 0and a channel-iron D, while the central or intermediate columns consisteach of a flat vertical plate 0 and two channel-irons D D. The verticalplates and the channel-irons which compose each column are firmly bracedand held at proper distance apart by bolts 01 d and are of any requiredheight, and the several columns of the structure may be connected bytie-rods at suitable points.

The brackets, which constitute the subjectmatter of this application andwhich are secured to the vertical columns and support the shelves, eachconsists of a vertical plate F, having at its inner edge a verticalflange G, which when the bracket is in position abuts or bears againstthe outer surface of the flange of the channel-iron D, and the rod G,which passes'thro'ugh a lug H, formed on or attached operationconvenient and effective.

to the plate F, and is bent or headed on its inner end so as to bearagainst the inner side of the channel-iron D and, conjointly with theflange G, clamp and rigidly secure the bracket in any position to whichit may be adjusted. The rod G extends horizontally to the outer edge ofthe bracket, or at least sufficiently far to accomplish the purpose forwhich it is intended and render its use and The rod Gis screw-threadedon its outer end and is preferably drawn lengthwise, so as to clamp theflange of the channel-iron D by a nut g, screwed onto its outer end andbearing against the lug 11. When the bracket is in position and the rodG drawn or tightened, its inner bent or headed end presses against theinner surface of the flange of the channel-iron D, while at the sametime the flange G of the bracket is forced against the outer surface ofthe flange of the channel-iron and the bracket thus rigidly secured inplace.

When the rod G instead of being bent laterally at its inner end, asshown in Fig. 1, is formed with a square or rounded head, as shown inFig. 3, the nut g may be dispensed with and the lug H or the flange Gformed with a threaded opening, serving as ascrew bearing for the rod G.4

When the rod G is simply bent or provided with a lateral projection onits inner end, as

shown in Fig. 1, it is inserted in a space back of the flange of thechannel-iron D by being turned so as to bring the bent portion of therod to a vertical position, and to enable the rod to be turned andafterward partially rotated, so as to interlock the bent end with thechannel-iron, the outer end of the rod G is formed with a notch for thereception of a screw-driver or is squared for the reception of a wrench.

When the rod G instead of being simply bent, as shown in Fig. 1, isheaded, as shown in Fig. 3, it is inserted in the column by beingdropped in from the open top of the latter or by being inserted inenlargement 7c of the slot 70 of the column, and after being brought toits proper position is tightened up by means of a screw-driver orwrench.

The shelves M M, which the bracket supports, may be either flat boardsor made of rolled or cast metal. The shelves are supported by thebracket by being made simply to rest upon the rods G. Instead of havingthe shelves so arranged that their under surfaces rest directly on therod G the ends of the shelves may be grooved or channeled horizontallyat m, so as to embrace the rods G, and instead of grooving or channelingthe ends of the shelves they may be formed with rabbets, which willallow the under surfaces of the shelves to fall slightly below the rodsGdo'r to be flush with the lower sides of the ro s.

Having described my invention, I claim as new and desire to secure byLetters Patent 1. A bracket for library-shelving composed of a verticalplate with a vertical flange at its rear edge and a threaded barextending from the front edge of the bracket through said verticalflange and having a head adapted to embrace a vertical column,substantially as described.

2. Abracketforlibrary-shelving consisting of a vertical plate having aflange at its rear edge, a lug at or near its front edge and a threadedrod or bolt extending through said lug and flange and having a headoutside said flange, substantially as described.

3. In library-shelving, the combination of a vertical column having avertical flange with a bracket composed of a leaf or plate, having avertical flange at its rear edge and alug at its front edge and athreaded bar passing through the lug and flange and having a headoutside said flange which contacts with said column and draws thebracket against the same, substantially as described.

4. The Within-described bracket forlibraryshelving, provided at itsinner end with a vertical flange and an adjusting-screw extended fromthe front end of said bracket rearwardly through the said verticalflange, and provided at the back of said flange with a clampinghead toembrace a supporting-standard, substantially as described.

5. The within-described bracket for libraryshelving, the same providedat or near its front end with a lug, and at or near its rear end with avertical flange, and a screw extending through both said lug andflange,and provided at the back of the latter with a clamping-head,substantially as described.

6. A bracket for library-shelving comprising a flat plate having alateral perforated projection at its inner edge and an adjustingscrewmounted thereon below the upper edge of the plate and having a headadapted to embrace a vertical column, said bracket being formed with anunobstructed space or opening from its inner to its outer edge on theaxial line of the adj usting-screw and having at its outer edge alateral projection pierced in alinement with the adjusting-screw so thatthe latter may be operated from the front edge of the bracket.

7. The combination with a channeled supporting column or standard andwith a bracket adapted to support one end of a shelf and having avertical laterally-extending flange at its inner end, of a clamping-headhaving a threaded shank passing through said flange, out of alinementwith the side wall of the bracket and capable of being operated from thefront of the bracket and a suitable guiding lug or ear located at thefront edge of the bracket and adapted to embrace or abut against theouter edge of the shelf, said lug being formed with an opening to guideand support the rod by which the clamping-head is operated.

8. The combination with an upright having an undercut groove of abracket provided with an adjusting draft-screw havinga clamping-head onits inner end adapted to engage with the overhanging flange on theupright said clamping-head having sufficient lateral extent to preventits withdrawal from the groove of the upright when turned to ahorizontal position but thin enough in cross-section to permit itsinsertion or removal from the groove when turned to a vertical position,substantially as described.

In testimony whereof I afiix my signature in presence of two Witnesses.
